Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow chart of the selective erase method for bistable liquid crystal screen that the embodiment of the present invention one provides, this reality
It applies example and is applicable to the case where selective erase is carried out to bistable liquid crystal screen, this method can be by the dress with selective erase function
It sets to execute, which can be the electronic drawing board etc. for being provided with bistable liquid crystal screen.As shown in Figure 1, this method specifically includes
Following steps:
Step 110, when detecting selective erase instruction, search pattern is switched to according to selective erase instruction.
Wherein, search pattern can be search and receive the mode of the checking signal of writing pencil transmission.In the present embodiment, electricity
Global erasing key and selective erase key are installed on sub- drawing board, when the user clicks after selective erase key, electronic drawing board inspection
Selective erase instruction input is measured, hence into search pattern, to search for the checking signal of writing pencil transmission.
Step 120, under search pattern, the checking signal that writing pencil is sent is received.
It wherein, may include authentication information in checking signal, such as the ID of writing pencil.Specifically, electronic drawing board is in
Under search pattern, when user, which is inverted writing pencil, to wipe, the touch-switch starting of writing pencil is triggered, writing pencil generates verifying
Signal, and checking signal is sent to electronic drawing board in the form broadcasted, at this point, electronic drawing board searches testing for writing pencil transmission
Signal is demonstrate,proved, and receives the checking signal.
Step 130, selective erase mode is switched to by search pattern according to checking signal.
Specifically, after electronic drawing board receives the checking signal of writing pencil transmission, according to checking signal by search pattern
Switch to selective erase mode.
Optionally, selective erase mode is switched to by search pattern according to checking signal, can be implemented by following manner: right
Checking signal is verified, if being proved to be successful, switches to selective erase mode by search pattern.
Wherein, the mode verified to checking signal can be the authentication information and electronic picture in checking signal
The information stored in plate compares, and if they are the same, is then proved to be successful, if not identical, shows that writing pencil does not have with electronic drawing board
It is matched, is then verified unsuccessful.After electronic drawing board is proved to be successful checking signal, local wiping is switched to by search pattern
Except mode.
Step 140, under selective erase mode, according to writing pencil input selective erase operation to bistable liquid crystal screen into
Row selective erase.
Under selective erase mode, the touch-switch of writing pencil is constantly in starting state, and writing pencil persistently generates verifying
Signal, electronic drawing board persistently receive the checking signal of writing pencil transmission.User's control writing pencil inputs part to electronic drawing board
Erasing operation, the selective erase operation that electronic drawing board is inputted according to writing pencil carry out selective erase to bistable liquid crystal screen.
